When people lie, it's common to break eye contact; but a liar may go the extra mile to maintain eye contact in an attempt to control and manipulate when you ask them a direct question. Here are 7 simple signs that someone may be lying to you:

they stand very still, in a rigid, catatonic stance devoid of movement;
they stare without blinking much or change their head position quickly;
they instinctively touch their mouth, cover vulnerable body parts or shuffle their feet;
their breathing becomes heavy, their shoulders rise and their voice becomes shallow;
they repeat words or phrases or they provide too much information, especially an excess of details;
it becomes difficult for them to speak; and / or
they becomes hostile or defensive and point a lot.

With the above signs in mind, it is important to remember that everyone acts and responds differently during times of stress, when nervous or feeling tense. When people lie, the body experiences a number of changes, including increased heart rate and blood flow and decreased salivary flow. Repetition of information is a way to buy a liar time as they attempt to gather their thoughts. Liars often talk a lot because they are hoping that, with all their talking and seeming openness, others will believe them.
